Ashley: Third Coast Interiors and specifically Guin are the most talented designer teams I've ever worked with on a commercial space. In fact, her work with our commercial space was so great that I'm having her completely redo our residential beach house and we are so excited to be able to work with her again. Her style is great, ideas are so creative, and she is professional and easy to work with.
Katharine: Guinevere is fantastic! She helped us with remodeling / designing most of a home we had purchased that needed a lot of updating. We are beyond pleased with the final outcome. Guinevere honored our preferences / tastes, but made suggestions that we would have never come up with on our own.
Laura: We really enjoyed working with Guinevere on our loft renovation. We completely gutted our two bathrooms and upgraded the rest of our loft, including the master bedroom. Guinevere was always professional and worked within our budget throughout the project. We had so much fun selecting materials and fixtures. I miss working with her and would recommend her to anyone looking for an interior designer.
Peggy: I loved working with Guin. She has an excellent sense of style and color. Our project expanded and ended up covering 5 rooms instead of 3. Most importantly, it was done on time and within budget.
We are always interested in collaborating with talented people. Please email firstname.lastname@example.org with your portfolio and resume.
